Quetiapine - daytime over-sedation by seroquel?

Hi, Love!
You're probably on too high a dose. I started at 50mg and worked my way up to 200mg over several weeks. A dosage higher than that gave me the morning groggies.
I've adjusted well to the 200mg dose.

It causes daytime fatigue and weakness for me, too. I've been taking 100 mg for several months and it's getting worse. I have vivid dreams. I have to nap mid-morning every day. I had previously been taking 50 mg without difficulty, but it was less effective for my insomnia. Starting tonight, I'm going back to 50 mg. Maybe that was the better dose for me - some relief for sleeplessness, but no drowsiness during the day. We'll see. Maybe you could ask your doctor about a reduced dosage.

I also suffer from chronic insomnia and take 500mg of Seroquel. Everyone reacts differently to everything in life. Having said that in my case I did get used to the med and know I am doing ok with it, no hang over.
Give it some time, so your organism can adjust to the medication.
